It's King Kong vs. Godzilla! Pox Virus Can Kill Cancer Cells

Results from a Phase I trial of Jennerex Inc.'s experimental cancer drug JX-594, which is based on the pox virus, demonstrated that after intravenous administration of a single dose of the drug, JX-594 was able to specifically replicate in metastatic tumors. At the highest doses tested, the drug led to tumor stabilization or regression in six out of eight patients.
